Abstract. As the vegetation in the Arctic changes, tundra ecosystems along the southern border of the Arctic are becoming greener and gradually giving way to boreal ecosystems. This change is affecting local populations, wildlife, energy exchange processes between environmental compartments, and the carbon cycle. To understand the progression and the implications of this change in vegetation, satellite measurements and surface models can be employed. However, in situ observational data are required to validate these measurements and models. This paper presents observational data from two nearby sites in the forest–tundra ecotone in the Tasiapik Valley near Umiujaq in Northern Quebec, Canada. One site is on a mixture of lichen and shrub tundra. The associated data set comprises 9 years of meteorological, soil and snow data as well as 3 years of eddy covariance data. The other site, 850 m away, features vegetation consisting mostly of tall shrubs and black spruce. For that location, 6 years of meteorological, soil and snow data are available. In addition to the data from the automated stations, profiles for snow density and specific surface area were collected during field campaigns. The data are available at https://doi.org/10.1594/PANGAEA.946538 (Lackner et al., 2022b).

气象、雪和土壤数据、二氧化碳、水和能量通量,来自魁北克北部森林苔原交错带的低北极山谷

摘要。随着北极植被的变化,北极南部边界的苔原生态系统变得更加绿色,并逐渐让位给北方生态系统。这种变化正在影响当地人口、野生动物、环境隔间之间的能量交换过程以及碳循环。要了解这种植被变化的进展和影响,可以使用卫星测量和地表模型。然而,需要现场观测数据来验证这些测量和模型。本文介绍了加拿大魁北克北部 Umiujaq 附近 Tasiapik 山谷森林-苔原交错带附近两个地点的观测数据。一个地点位于地衣和灌木苔原的混合地带。相关数据集包括 9 年的气象、土壤和雪数据以及 3 年的涡度协方差数据。另一个地点距此 850 米,植被主要由高大的灌木和黑云杉组成。对于那个位置,有 6 年的气象、土壤和雪数据可用。除了来自自动化站的数据外,在野外活动期间还收集了雪密度和比表面积的资料。数据可在 https://doi.org/10.1594/PANGAEA.946538 获取(Lackner 等人,2022b)。
